Direct loading of a Sr magneto-optical trap from a thermal atomic beam
Naohiro Okamoto, Takumi Sato, Takatoshi Aoki +1
We demonstrate direct loading of a strontium (Sr) magneto-optical trap (MOT) from a thermal atomic beam in a single-chamber vacuum system. The MOT operates without a Zeeman slower,…
Direct Measurement of the Decay Rate in Strontium
Naohiro Okamoto, Takatoshi Aoki, Yoshio Torii
We report the first direct experimental determination of the branching ratio of the transition and the decay rate of the $5s5p\,{}^1P_1 \to 5s4d\,…
Analyzing the optical pumping on the transition in a magneto-optical trap of Sr atoms
Naohiro Okamoto, Takatoshi Aoki, Yoshio Torii
We explore the efficacy of optical pumping on the () transition in a magneto-optical trap (MOT) of Sr atoms. The number of trapped…
Limitation of single-repumping schemes for laser cooling of Sr atoms
Naohiro Okamoto, Takatoshi Aoki, Yoshio Torii
We explore the efficacy of two single-repumping schemes, () and (), for a ma…
